Did someone call the Harramedics? Gallant Harry Styles helps an injured teen following One Direction fan stampede in New York

He’s back in London following a whirlwind promotional tour of the United States, but One Direction star Harry Styles bid farewell to America after coming to the rescue of an adoring, and very injured teenage fan.

The 19-year-old singer created a predictable frenzy when he stepped out for some last minute shopping at a Polo Ralph Lauren store in New York’s SoHo district on Tuesday.

Fans had braved freezing temperatures to get a glimpse of tousle-haired Harry before he returned to the UK with his bandmates, and they were duly rewarded when he made an appearance in Lower Manhattan.

But as the throng clamoured to get his attention, one teenage girl was pushed to the ground, injuring her leg in the process.

Witnessing the accident, Harry, who publicly thanked fans for ‘changing his life’ during a recent appearance on The Jonathan Ross Show, promptly came to the rescue by helping the tearful girl to her feet.

The band travelled from one side of the US to the other while they promoted new album Midnight Memories, which was released on Monday.

Having returned to the UK, Harry was out and about in London on Wednesday looking every inch the hipster.

Dressed in skinny jeans, brown chelsea
boots, grey T-shirt, lumberjack shirt a brown shearling coat, the singer accessorised his look with a silver pendant, dark
glasses and the same khaki headband he wore while helping his young fan the previous day.

and revealed the dates for their upcoming Where We Are tour.

With their breath visable in the air, it was obviously a cold morning in the New York central park.

Liam congratulated their fans on being so devoted: ‘This is so nice. We can’t believe how many people have showed up in the cold for us.

‘We don’t usually get up this early.’ Harry interjected.

The boys’ album Midnight Memories has only been on iTunes for a matter of hours, yet it’s already at number 1 in almost 200 countries.

Talking about their success around the world, Louis said: ‘I think it’s such a hard thing to contemplate. Me and Zayn were sat in a room yesterday and we had a little bit of a toast and a celebration. But it’s such a hard thing to get your head around. It’s a testament to our fans.’

It’s well known that the boys have had more of an input with this, their third studio album – and they say they were nervous about how it would be received.

Harry said: ‘If you ask anyone who’s put out music that you’ve written, music that really means something to you, it’s you and it’s you in the songs – it always adds more pressure.

‘We were definitely nervous about it, for sure. To see that it’s been received so well is nice. We’re proud and really happy.’

Liam added: ‘It’s incredible. We can’t believe we got to write on the album this year. Like Louis said it’s a testament to our fans who’ve got us in this position where we have the power to be able to sit and write and enjoy our own music. It’s ace.’

The band held a special 1D day on Saturday which was a massive success and the biggest YouTube music live stream ever.

It
trended on Twitter at #1 Worldwide for 8 hours, with 9 million mentions
of 1DDay and 1DDay Live, and 12 million mentions of all related
hashtags in just 7 hours. Just another small step towards world domination for the group of teenage boys who met on the X Factor.
